ectodermal cells overlaying the notochord become tall columnar producing neural groove the dorsal margins of the neural groove merge medially forming a neural tached from the tube and collec.

Gastrulation is a phase early in the embryonic development of most animals, during which the single-layered blastula is reorganized into a multilayered structure known as the gastrula. .
